Propagation of plants by asexual means, i.e. without seeds. This involves planting different parts of a plant (shoots, root parts or, as with many flowers, bulbs) in the soil, from which roots and shoots can then develop. In nature, sexual or generative propagation usually takes place, i.e. the product is genetically different from the parents, which normally produces offspring that are strong enough to survive. However, there are also some plants with natural vegetative reproduction (e.g. various types of moss). Vegetative propagation is used in plant breeding to produce plants in large quantities. In viticulture, this means propagation by planting mostly blind vines of a mother vine. Since the vine is extremely heterozygous (split-yellow), propagation, i.e. the production of vines in nurseries, is basically carried out by vegetative means.
